Mark Milstein, director of theCenter for Sustainable Global Enterprise at Cornell's Johnson Graduate School of Management, says the recent financial crisis showed that traditional investment vehicles were fallible, and underscored the importance of the sort of long-term strategies that are central to impact investing. The sector is predicted to grow to $500 billion by 2014, according to the nonprofit Global Impact Investing Network.
